Skin Scan: New iPhone App to Detect & Track Moles

During the summer, most people are acutely aware of sun damage. Long days outside without sunscreen may result in sunburns, new wrinkles, and possibly even skin cancer. If your next appointment with your dermatologist is months away but you’re concerned about possibly abnormal moles, check out the new Skin Scan app for iPhones.

Skin Scan is a $4.99 app that “scans” moles and lesions to detect if they are low-risk, medium-risk, or high-risk. The app uses an algorithm to examine the skin surrounding the mole and the mole itself to determine if the mole is an abnormal shape, size, or color. You can also track moles with the app; a mole that changes size, shape, or color could be an indication of melanoma or other skin cancers.

Skin Scan also includes another interesting feature: location mapping. When a mole is deemed low-, medium-, or high-risk, the location of the user and the results are recorded and mapped. Depending on the sample size, Skin Scan may eventually produce a fairly accurate map depicting what locations are the most dangerous in terms of skin damage from the sun.

Like most new developments in the medical and dermatological field, Dr. Zimmet urges patients to download the app with a grain of salt. It’s important to beware of false negatives, where the scan reads a normal mole that is actually not normal. Unless we understand the rate of false negatives, determined in a well-controlled study, it’s critical not to rely on the results of the scan when deciding whether or not you should see your dermatologist. So, it’s strongly advised that you have regular check-ups with your dermatologist, even if you believe that none of your moles are abnormal.
